Rain caps with the overall dimension providing an angle of at least 27° from the vertical of a line from the edge of the rain cap to the edge of flue are considered to meet the requirement under no wind conditions. SIST EN 16475-7:2016
EN 16475-7:2016 (E) 11 It is recommended that the size of the rain cap is at least of the same size as the exterior dimension of the top of the chimney in order to protect the top of the chimney from rain where it is otherwise not protected. 4.6.3 Flow resistance of the rain cap The manufacturer shall declare the coefficient of flow resistance of the rain cap. The declared value shall be determined according to the test method described in 5.3.2 or obtained from data given in Table B.1. A zeta value of maximum 1.5 is recommended.
